I II 7 wait. t me Den t of l li i 'e gApplication Ncyember -This invention relates to an improvedovenoflue 'deflector 'for domestic gas. ranges. In a gas' ran'ge, the flue for conductin the products of combustion upwardly from the oven "compartment: requires a deflector on its upper en for directing the escaping products forwardly over the cooking top, away from the: wall'behind :the range,- and, inasmuch as' thisfdefl'e'ctor: is .one ofthe most conspicuous parts of='the.range,:it:-is very important that, besides beingfefllcient and serviceable, it beof attractive appearance. .YIt iS, therefore; the principal object of my inventionto provide a multiple louvered fluedeflector' in which the parallel'louvers of graduated height; lowest in front and highest in rear, give not only the :desired 'efiiciency' of operation} but alsopresent: .a neat and attractiveappearance- I s i Another object of 'my invention is to provide a flue" deflector having parts all or most ofwhich may be stamped from sheet metal and assembled "together ina relatively few simple operations, so

that the device is available at a reasonably low cost. Still another-object of my invention is the pro- M vision of a flue deflector-which involves a minimum number of simple stamped sheet metal parts, and which, when assembled, isdesigned to be easily mounted ona flue without the addition of other parts to secureit'thereon: In the accompanying drawing: i to Fig. 1 .is a perspectiveview of the" flue deflector as an assembled parton. the support for the condiment iset; and timer, adapted tg mounted on the back rail of a domesticlgas range; Fig. 2is a face view of a stamped and'pfilrtially formed sheet metal blank from which the main body part. o the ef e or is., o me v Fig, 3 is a face viewoi the middle louver; ,--Fig. 4 is a planl view of the flue deflector in assembled form ready for application to theflue; "4

Only the. extreme upper} endportion of the flue is shown in; Fig. 5,; namely; the portion extending above the backlail a;DQIYfiQ 1J1QfQWh hf 'dicated at 9,'-on, top oi which the assembly appearing. inFig. L1 ;is, mounted. The extreme upper :end portion of, the. flue llilwis enclosed in a jacket l I} which serves also ,to space thetwoplates' l2 and I3: The latter is. adapted to rest on; top of and beuseuredto the;baok'rail ofrthe range with the plate 1! 2 and 'spacingujacket I"! as by throu h bolts (not shownyextending vertically inside the jacket from the "plugs: Ila. ,cl ovvnwardly through the top of the backrail jand'receivin wing nuts on their lower, ends; under t tgpwall of the back rail. The'plate Hriorms'a convenient shelf for support of the timer -li5 ;and condiment shakers 16; Aone-piece bent wire: retaining rail l1 fits in holes in the upper plate lland has its depending end portion, lflapentered-through a hole in the lowerplate: I 3 and suitably secured in place from beneath the.:l'atter.; The upperplate I 2, as

indicated at M in Figs. 5- and 'l hasv an opening defined b-ya. downwardly bent flange into'which the end of .the flue l0 .projects; and it is over this opening thatlthe frame l8 of the flue deflector 0f my invention is mounted on the upper plate l2,

in register with'therend of the flue III. The parts i ll, I2 and I3: are :all preferably porcelain enamelled-to match the porcelain enameledbac k rail 9. However, the framemlflj and the rest of the flue deflector is preferably of aluminum to avoid corrosion. 2 v

I consists of a rectangular-shaped piece of sheet metal formedtoprovide an integral outer, downwardly. directed circumferential flange l to rest upo'n -therplate l2 in outwardly spaced relation to the'uupper. end of the'fiue l0, As illustrated in Fig.2, the blank 'for frame I8 is punched to provide the longitudinal opening 20 having identical forked end portions defining inwardly extending lugs 12L and..22. $10, 23 and 24 =are also provided in the opposite-ends of the blank for the reception of lugs for 'support of a middle louver 25;. The portions 26a and Tie of the partially formed blank shown in Fig.2 are subsequently bent upwardly, to form .a larger 'rear lo'i'i'ver 26 and; a? smaller front louver 21, ass'hown in FigsJl fi, the two louvers being paralleland of substantially: the same length and inclined forwardly at the same angle, as clearly shown in the'drawing V w v. Q i P i The middle louvler, 25 is stamped fromsheet f'metal'to the form shown in Eig.3,a,its1 opposite lower corners being: cut ta form integral downsite'ends of said slot formed by said V-shaped having an elongated slot'provided therein that is forked at opposite ends, the portions on the opposite longer sides of said slot being suitable for louvers and the generally V-shaped portions at opposite ends of said slot being Suitable for attaching lugs,'louvers on said body formed by said first named portions bent out of the plane of said body along lines substantially parallel to the edges of said portions forming the opposite longer sides of the longitudinal slot, and lugs on said body at the opposite ends of said slot formed by said V-shaped portions bent from the plane of saidbody in the opposite direction relative to said louvers to engage with supporting means and thereby secure the unit in fixed position, one of the louvers being of relatively narrow but uniform width from end to end and the other of said louvers being of relatively wide but uniform width from end to end, and the two louvers being bent at substantially the same acute anglerelative to the plane of said body and so as to project from said body'in the same direction.

portions bent from the plane of said body in the opposite direction relative to said louvers, the body having two other slots provided therein in alignment with one another and in substantially parallel relation to the first named slot the last named slots being elongated so that the inner end portion thereof are included in the' V- shaped lug portions bent from said body, and another louver disposed between the first men-- tioned louvers with the opposite ends thereof entered in said last namedslots for rigid support of the louver on said body, said louver also having means on the ends thereof for detachably securing the same against displacement from said slots. 7

7. In combination, a support having an open 1 ing provided therein, a conduit having a disportions bent from the plane of said body in the opposite direction relative to said louvers, the

body having two other slots provided-therein adjacent said V-shaped end portions, and another louver disposed between the first mentioned louvers and having means on the ends thereof entered in said last named slots forsupport of said louver on said body.

6. A louver unit comprising a sheet metal body having an elongated slot provided therein that is forked at opposite ends, the portions on opposite sides of said slot being suitable for louvers and the generally V-shaped portions at oppositeends of said slot being suitable for attaching lugs,

louvers on said body formed by said first named portions bent out of the plane of said body along lines substantially parallel to the edges of said portions forming the opposite'sides of the longitudinal slot, and lugs on said body at the oppocharge end portion extending into said opening, and a louver unit comprising a sheet metal body member mounted on said support in register with the end of said conduit and having louver portions bent outwardly from the plane of said body adjacent opposite sides of the conduit and extending at angles to the body in the same direction for deflecting a flow discharged from said conduit in a, predetermined direction relative to said conduit and support, and another louver,

comprising a supporting portion detachablyfa mounted on said body' and extending across the middle of said conduit in a plane parallel with the axis thereof, and a deflecting portion bent in angular relation to the supporting portion outside said body and in the same" direction as the first mentioned louversr 8. A louver unit comprising a one-piece sheet metal body member having an elongated opening provided therein, opposite'sides of theopening defining edges of louver portions, and louvers formed by said portions bent out of. the plane of said body on lines in spaced parallel relation to said edges and substantially parallel to one another, another intermediate louver having means forsecuring the opposite end portions thereof to i said body for support of the louver in substan-.

tially parallel relation to the first mentioned louvers, and a transverse brace intermediate the ends of said last mentioned louver secured tosaid louver and having abutment at its opposite ends with the first mentioned louvers to'holdthe in-' termediate louver in fixed spaced relation to' th first mentioned louvers. 1 HAROLD H.
